Downloading a Firmware Image

You can upgrade the operational firmware in the SecureStack C3 switch without physically opening the switch or being in the same location. There are two ways to download firmware to the switch:

•Via TFTP download. This procedure uses a TFTP server connected to the network and downloads the firmware using the TFTP protocol. For details on how to perform a TFTP download using the copy command, refer to “copy” on page 3‐45. For information on setting TFTP timeout and retry parameters, refer to “set tftp timeout” on page 3‐47 and “set tftp retry” on page 3‐48.

•Via the serial (console) port. This procedure is an out‐of‐band operation that copies the firmware through the serial port to the switch. It should be used in cases when you cannot connect the switch to perform the in‐band copy download procedure via TFTP. Serial console download has been successfully tested with the following applications:

–HyperTerminal Copyright 1999

–Tera Term Pro Version 2.3

Any other terminal applications may work but are not explicitly supported.

The C3 switch allows you to download and store dual images. The backup image can be downloaded and selected as the startup image by using the commands described in this section.

Downloading from a TFTP Server

To perform a TFTP download, proceed as follows:

1.If you have not already done so, set the switch’s IP address using the set ip address command as detailed in “set ip address” on page 3‐11.

2.Download a new image file using the copy command as detailed in “copy” on page 3‐45.

Downloading via the Serial Port

To download switch firmware via the serial (console) port, proceed as follows:

1.With the console port connected, power up the switch. The following message displays:
